java.lang.OutOfMemoryError 调用 getDrawable() 时

Question

我收到以下内存不足错误，我不确定为什么。

Failed to allocate a 1860508 byte allocation with 905740 free bytes and 884KB until OOM

我正在使用 5 级资源来指示 wifi 状态，这是我正在使用的代码

    WifiManager wifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);

    // Level of current connection
    int rssi = wifiManager.getConnectionInfo().getRssi();
    int level = WifiManager.calculateSignalLevel(rssi, 5);
    Drawable db = getDrawable(R.drawable.stat_sys_wifi_signal);
    db.setLevel(level);
    wifiMenu.setIcon(db);

图片大小相同 (512x512)。

参考其他答案，我的清单中有 largeheap。

如有任何帮助，我们将不胜感激。

Answer 1

Use TinyPNG

TinyPNG uses smart lossy compression techniques to reduce the file size of your PNG files. By selectively decreasing the number of colors in the image, fewer bytes are required to store the data. The effect is nearly invisible but it makes a very large difference in file size!

使用此 link 压缩所有图像。

在您的 Android 应用程序中使用之前减小所有图片的大小。

请务必阅读@mudit_sen 提供的文档Loading Large Bitmaps Efficiently。

希望对您有所帮助。
